如何使用 FCM 使用 php 脚本向多个设备发送推送通知？

Question

我是使用 FCM 从 php 向 Android 设备推送通知的新手。从 android 端，我生成了 FCM reg_id 并通过 php 脚本将其发送并存储到 mysql 数据库中。现在，我想同时从 php 脚本向多个 android 设备发送通知。

这是发送推送通知时使用的 php 脚本：

1.firebase.php (reference link)

 <?php

class Firebase {

// sending push message to single user by firebase reg id
public function send($to, $message) {
    $fields = array(
        'to' => $to,
        'data' => $message,
    );
    return $this->sendPushNotification($fields);
}

// sending push message to multiple users by firebase registration ids
public function sendMultiple($registration_ids, $message) {
    $fields = array(
        'registration_ids' => $registration_ids,
        'data' => $message,
    );

    return $this->sendPushNotification($fields);
}

// function makes curl request to firebase servers
private function sendPushNotification($fields) {
    
    require_once('config.php');

    // Set POST variables
    $url = 'https://fcm.googleapis.com/fcm/send';

    $headers = array(
        'Authorization: key=' . FIREBASE_API_KEY,
        'Content-Type: application/json'
    );
    // Open connection
    $ch = curl_init();

    // Set the url, number of POST vars, POST data
    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    // Disabling SSL Certificate support temporarly
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

    // Execute post
    $result = curl_exec($ch);
    // echo "Result".$result;
    if ($result === FALSE) {
        die('Curl failed: ' . curl_error($ch));
    }

    // Close connection
    curl_close($ch);

    return $result;
   }
 }

?>

2.push.php : (reference link)

<?php

class Push {

// push message title
private $title;
private $message;
private $image;
// push message payload
private $data;
// flag indicating whether to show the push
// notification or not
// this flag will be useful when perform some opertation
// in background when push is recevied
private $is_background;

function __construct() {
    
}

public function setTitle($title) {
    $this->title = $title;
}

public function setMessage($message) {
    $this->message = $message;
}

public function setImage($imageUrl) {
    $this->image = $imageUrl;
}

public function setPayload($data) {
    $this->data = $data;
}

public function setIsBackground($is_background) {
    $this->is_background = $is_background;
}

public function getPush() {
    $res = array();
    $res['data']['title'] = $this->title;
    $res['data']['is_background'] = $this->is_background;
    $res['data']['message'] = $this->message;
    $res['data']['timestamp'] = date('Y-m-d G:i:s');
    return $res;
}

}

3.test.php

 <?php
include_once('config.php');
require_once('DB_Functions.php');
require_once('firebase.php');
require_once('push.php');



$db = new DB_Functions();
$firebase = new Firebase();

        $ucategory = $_POST['user_category'];
        ChromePhp::log('U category '.$ucategory);

        // notification title
        $messageTitle = isset($_POST['message_title']) ? $_POST['message_title'] : '';
        
        // notification message
        $messageToSend = isset($_POST['message_to_send']) ? $_POST['message_to_send'] : '';
        ChromePhp::log('Message Title '.$messageTitle." Message:".$messageToSend);

        $userslist_with_fcm_id = $db->getUsersFCMId($ucategory);
        ChromePhp::log('FCM LIST  '.$userslist_with_fcm_id->num_rows);
        // var_dump($userslist_with_fcm_id);


        $push->setTitle($messageTitle);
        $push->setMessage($messageToSend);

        $push->setIsBackground(FALSE);

        $json = '';
        $response = '';

        if ($userslist_with_fcm_id->num_rows > 0) {
             while ($row = mysqli_fetch_array($userslist_with_fcm_id)){
             
             ChromePhp::log('FCM ID  '.$row['fcm_id']);
             
             $json = $push->getPush();
             
             $regId = $row['fcm_id'];
             $response = $firebase->send($regId, $json);
                                            }
                                        }
                                  
       else{
              echo '<h3>Oops ! You got empty data</h3>';
           }
        var_dump($response);       
}

所以，到目前为止，我已经尝试从数据库和调用发送方法中迭代所有 reg_id，但它没有向任何设备发送通知。

Answer 1

尝试将多个设备的设备 ID 作为数组发送。在你的情况下，

$registration_ids 必须是设备 ID 数组。

例如

$registration_ids = array('Device ID 1', 'Device ID 2');

Answer 2

如果您要通过终端发送通知，curl 命令的数据部分将如下所示：

{
"registration_ids": ["device_token_1", "device_token_2"],
"notification": {
    "body": "Hello",
    "title": "Hello",
    "vibrate": 1,
    "sound": 1
 }
}

PHP 代码：

$body = array(
        'registration_ids' => array("device_token_1", "device_token_2"),
        'notification' => array('body' => 'Hello', 'title' => 'Hello', 'vibrate' => 1, 'sound' => 1)
    );

Answer 3

如果您想发送给多个用户，请使用“registrations_ids”代替“to”：

$fields = array
(
    'registration_ids'  => $tokens,
    'notification'   => $msg


);

其中 $tokens = array("设备令牌 1" , "设备令牌 2");

如果您想发送给单个用户，请使用 'to' ，例如

$fields = array
(
    'to'  => $token,
    'notification'   => $msg


);

其中 $token = "设备令牌 1";

Answer 4

$notification_data = $this->common->get_all_record('table name',array()); //get all id from table

            if($notification_data != NULL){
                foreach ($notification_data as $notification_data_row) {
                    $registrationIds = $notification_data_row['token'];
                #prep the bundle
                    $msg = array
                        (
                        'body'  => 'body msg',
                        'title' => 'title',
                        'icon'  => 'myicon',/*Default Icon*/
                        'sound' => 'mySound'/*Default sound*/
                        );
                    $fields = array
                        (
                        'to'            => $registrationIds,
                        'notification'  => $msg
                        );
                    $headers = array
                        (

一次向多个用户发送 Firebase 通知

将多个 firebase 令牌添加到数组中。

$token_ids = array('token1', 'token2');

将令牌传递给下面显示的函数

使用下面显示的功能，您还可以发送带有通知的图像

如果您不想发送任何图像，则只需传递空字符串

sendFirebaseNotification($token_ids ,"notification title", "message", "image_url");

我用这个功能

function sendFirebaseNotification($fb_key_array, $title, $message, $imageURL){
    $authorization_key = "your_auth_key";

    $finalPostArray = array('registration_ids' => $fb_key_array,
                            'notification' => array('body' => $message,
                                                    'title' => $title,
                                                    "image"=> $imageURL),
                            "data"=> array("click_action"=> "FLUTTER_NOTIFICATION_CLICK",
                                            "sound"=> "default", 
                                            "status"=> "done")); 
    
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,"https://fcm.googleapis.com/fcm/send");
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,json_encode($finalPostArray));  //Post Fields
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Authorization: key='.$authorization_key));
    $server_output = curl_exec ($ch);
    curl_close ($ch);
    //echo $server_output; 
}

以下是发送通知的简单脚本。试试这个。

<?php 
$tokens = array('token_1','token_2','token_3');
$title = "Title Here";
$msg = "Subtitle or description Here";
//Custom Parameters if any
$customParam = array(
   'redirection_id' => '2',
   'redirection_type' => 'post_page' //'post_page','category_page','blog_page'
);
push_notification_android($tokens,$title,$msg,$customParam);
function push_notification_android($tokens,$title,$msg,$customParam) {
$url = 'https://fcm.googleapis.com/fcm/send';
$api_key = 'fcm_server_api_key';
$messageArray = array();
$messageArray["notification"] = array (
    'title' => $title,
    'message' => $msg,
    'customParam' => $customParam,
);
$fields = array(
    'registration_ids' => $tokens,
    'data' => $messageArray,
);
$headers = array(
    'Authorization: key=' . $api_key, //GOOGLE_API_KEY
    'Content-Type: application/json'
);
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Disabling SSL Certificate support temporarly
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
// Execute post
$result = curl_exec($ch);
if ($result === FALSE) {
    echo 'Android: Curl failed: ' . curl_error($ch);
}
// Close connection
curl_close($ch);
return $result;
}
?>
